Study arms

  • Active comparator
    Maraviroc

    For subjects assigned to the maraviroc group, subjects will receive maraviroc at 300mg by mouth twice daily for 24 weeks in addition to taking their current anti-HIV medication. For subjects on ritonavir, the dose of maraviroc will be 150mg by mouth twice daily.

Interventions

  • DrugMaraviroc

    For subjects assigned to the maraviroc group, they will receive maraviroc at 300mg by mouth twice daily for 24 weeks in addition to taking their current anti-HIV medications. For subjects on ritonavir, the dose will be reduced to 150mg by mouth twice daily for 24 weeks.

  • Drugplacebo

    For subjects assigned to the placebo group, they will receive a matching placebo pill 300mg to be taken by mouth twice daily for 24 weeks in addition to taking their current anti-HIV medications.
